Ads not being blocked in Chrome Posted August 31 38 minutes ago, exile360 said: I'd use both only because I know how these block lists work. Yes, there will be some overlap, however you're also going to run into plenty of cases where one will block an ad or tracker that the other doesn't. They don't fight the way that two AV's analyzing the same file/process would. They are both inserted into the browser's stack and analyze traffic/connections and if they see a match with their block list they block the connection, and if a different extension got there first/blocked it already they do nothing and maybe log an error. There is no 'conflict' going on that could cause the browser to lock up or both extensions to 'fail' because both tried to block the same thing. Exactly, I turned my ublock just to test what Ron was seeing, I turned it back right after. I do not think at this stage of development that the MB extension will block anything as close as Ublock Orign out of the box or with the extra filter lists I add.
